I have a suggestion re the Live Audio - The RadioReference Wiki:
In the Alternative Broadcasting Clients section, Nicecast is listed for MAC OS X Clients.
An Alternative Broadcasting Method I would suggest to add for streaming without a computeris this:
Barix Instreamer 100 Network Audio Encoder
Pro Audio Gear: Barix Instreamer 100 Network Audio Encoder
This is a great alternative to using a computer.
Hope you can add this alt to the list.
